The fast-food franchise is serving its signature fries in cheerful rainbow-colored boxes at participating locations throughout the greater California Bay Area, as well as at some D.C. locations.

"McDonald's has always been a company that has supported diversity and inclusion of its employees and extended McDonald's family," McDonald's spokesperson Kim Knapp said in a statement. "We are proud to create an inclusive culture where everyone feels valued, appreciated and supported. As an official sponsor of this year's Pride festivities, we looked for a unique way to bring that celebration into our restaurants throughout the Greater Bay Area."

The LGBTQ-friendly fries arrive just as San Francisco prepares for its annual Gay Pride Celebration. Events include a rally and two days of speakers and performers at a Civic Center stage.

The rainbow fries will be available throughout the month of June.
